Testing of valves - Fire type-testing requirements (ISO 10497:2022)

This technical specification defines the essential requirements for evaluating the fire resistance of valves, aligning with international guidelines established for industrial safety. It outlines the test procedures necessary to determine how specific valve designs maintain functionality and structural integrity when exposed to high temperatures and flames. The document details the setup of test equipment, the preparation of specimens, and the acceptance criteria for various valve types used in critical systems. By following these guidelines, manufacturers and testing laboratories can ensure consistent assessment methods. The scope covers the determination of leakage rates and the ability to shut off flow under fire conditions. It addresses the performance limits of the sealing elements and the metal body during exposure to the fire test flame. This approach facilitates international trade by harmonizing the evaluation of valve safety across different regions and sectors. The standard provides a unified framework for assessing whether a valve meets the necessary safety thresholds for operation in fire scenarios.
